PLOW.

SPECIFICATION forming part of Letters Patent No. 449,565, dated March31, 1891.

Application filed August 25, 1890. Serial No. 363,061. (No model.)

v able others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in plows; and it consists incertain novel features to be hereinafter described and claimed,reference being had to the accompanying d rawings, in which- Figure 1 isa top plan viewof my plow complete. Fig. 2 is a perspective view of thesame with the left-hand side beam removed. Fig. 3 is a perspective viewshowing the right-hand beam removed. Fig. 4 shows both side beamsremoved, and Fig. 5 is a perspective view showing the rear section ofthe middle beam removed.

The same numeral references indicate corresponding parts in all thefigures.

The object of my invention is to provide a combined right and left handdouble-shovel plow, with the ordinary cultivator, single shovel, and thecovering or cultivating doubleshovel plow having its shovels directlyopposite each other.

Referring to the several parts of my combined plow by their designatednumerals, 1 indicates the center beam, the front end of which terminatesin the usual clevis-hook 2, while to its rear end is removably securedthe removable curved section 3, to the lower end of which is secured theshovel or blade at. To the left-hand side of the front end of the beam 1is bolted the front end of the left-hand beam 5, carrying at its rearcurved end the shovel-blade 6, while to the right-hand side of thecenter beam 1 is bolted the front end of a right-hand beam 7, carryingat its rear end a shovel-blade S. The side beams curve outward as theyextend backward, as shown, so that their rear ends are at a suitabledistance apart, the side beams being shorter than the middle beam,bringing their blades in advance of the blade of the latter.

A rod 9 passes transversely through an opening in the center beam 1, andis threaded, as

shown, and inner nuts 10 10 are screwed tight on the rod on each side ofthe center beam to secure the rod to this beam. The ends of thisthreaded rod pass through openings 11 in the side beams, which areslightly larger than the rod, and the pairs of adjusting-nuts 12 13 arescrewed on the ends of the rod on the outer and inner sides of the sidebeams, as shown. that by turning these adj Listing-nuts the rear ends ofone or both of the side beams can be adjusted in or out, as will bereadily seen, to regulate their distance from the center beam.

My combined plow can be arranged and used as an ordinary cultivator, asshown in Fig. 1. By removingthe left-hand side beam it can be used as aright-hand double-shovel plow, as shown in Fig. 2. By removing theright-hand side beam it can be used as a lefthand double-shovel plow.Then both side beams are removed,it forms an ordinary single The objectof this arrangement is plow, while by removing the rear section 3 of themiddle beam, with its blade, the plow forms a covering-plow, theopposite blades of which will run on opposite sides of and cover in therow, as will be readily seen by reference to Fig. 5 of the drawings.

To the forward end of the left-hand beam is secured to the side thereofa clevis 14, to which the horse is attached when the plow is used forcovering in a row, as shown in Fig. 5, this device permitting of thehorse walking on the side of the row instead of on top of it.

When the plow is used as an ordinary cultivator, as a single plow, or asa right-hand or left-hand double-shovel plow, as shown in Figs. 1, 4, 2,and 3, respectively, the handles 15, the lower ends of which are boltedto the rear part of the middle beam proper, have secured to them theupper ends of braces 16 16, the lower ends of which are bolted to theremovable section 3 of the middle beam; but when this section isremoved, as shown in Fig. 5, to change the plow to a covering-plow, thehandles are braced by braces 17 17, the lower ends of which are boltedto the side beams, as shown.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, manner of adjusting, andadvantages of my invention will be readil understood.

It will be seen that my new and improved blade, the removable side beam7, having all combined plow is simple and strong in 0011- end blade, andthe removable side beam 5, struction, and that it can be readily changedhaving an end blade and having the side to form, practically, fivedifferent kinds of clevis 1-L secured to the side of its forward 15plows, and can thus be used to perform the I end, substantially as setforth.
